How do I edit prices for individual vehicles?

Answer:

Once you open the Remora Administrative Portal and select Edit Vehicles under the Inventory Mods tab (glance over how to access edit vehicles), click on the green EDIT button (pictured below) to the far right of the corresponding row.

This will take you to the Edit Vehicle screen (previewed below) with all of the related fields you can modify.

To change the MSRP/Base price or Internet price, enter the new value or use the up and down arrows (illustrated below).

Then, click on the green SAVE CHANGES box (depicted below) that appears near the top of the page.
